Folic acid inowanzo shandiswa semushonga.In vitro uye in vivo zvidzidzo zveganda zvino zvinoratidza kugona kwayo kubatsira muDnA synthesis uye kugadzirisa, kukurudzira kutendeuka kweserura, kuderedza makwinya, uye kukurudzira kusimba kweganda.Pane chimwe chinoratidza kuti folic acid inogona kudzivirira DnA kubva kuV-induced kukuvara.Folic acid inhengo yevhitamini B yakaoma uye inowanzoitika mumashizha ane mashizha.
Zvinyorwa zvinowanzoratidza kuti mavhitamini eB haakwanise kupfuura nepakati peganda uye, naizvozvo, haana kukosha mupamusoro peganda.Zviyedzo zvemazuva ano zvinoratidza, zvisinei, kuti vhitamini B2 inoshanda semakemikari reaction accelerator, inosimudzira kushanda kwetyrosine derivatives musuntan-inomhanyisa kugadzirira.
Folic Acid inonyungudika mumvura b-complex vhitamini inobatsira mukuumbwa kwemasero matsvuku eropa, inodzivirira mamwe anemias, uye yakakosha mune yakajairika metabolism.high-temperature processing inokanganisa kugadzikana kwayo.inonyanya kuchengetwa pane yakaderera pane yekamuri tembiricha.inonziwo folacin.inowanikwa muchiropa, nzungu, nemiriwo yakasvibira.
vhitamini inodiwa kugadzira DNA, kuitisa DNA kugadzirisa uye methylate DNA, inoshandawo se cofactor mune biological reactions inosanganisira folate.
